What is Esterified Copolymer?
Esterified Copolymer is a functional polymer material synthesized through esterification modification of copolymer precursors. It is typically formed by first copolymerizing two or more monomers (such as olefins, acrylic monomers, or vinyl monomers) to form a copolymer backbone, followed by esterification reaction with alcohols, acids, or other esterifying agents. This modification introduces ester functional groups into the molecular structure, which endow the polymer with unique chemical and physical properties, bridging the characteristics of the original copolymer and ester compounds for targeted performance adjustment.
Features of Esterified Copolymer?
Esterified Copolymer exhibits a range of outstanding features tailored to its molecular structure and modification degree. It has excellent compatibility with various organic solvents, resins, and base materials, enabling stable blending without phase separation. It also possesses good thermal stability, maintaining structural integrity and performance under moderate temperature conditions, along with adjustable mechanical properties such as flexibility and toughness. Additionally, the ester groups in its structure contribute to enhanced adhesion, dispersibility, and surface activity, and its functional characteristics can be customized by adjusting the type of monomers, esterification degree, and molecular weight, making it adaptable to diverse application requirements.
Applications of Esterified Copolymer?
Esterified Copolymer finds widespread applications across multiple industrial fields due to its versatile properties. In petroleum processing, it is commonly used as a pour point depressant, viscosity reducer, or demulsifier, effectively improving the low-temperature fluidity and separation efficiency of crude oil. In the coatings and adhesives industry, it serves as a film-forming agent, plasticizer, or adhesion promoter, enhancing the coating's durability, gloss, and adhesion to substrates. It is also utilized in plastic modification to improve the processing performance and compatibility of polymers, as well as in textile auxiliaries, surfactants, and advanced material formulations, playing a key role in optimizing product performance in various scenarios.
Price of Esterified Copolymer?
The price of Esterified Copolymer is influenced by multiple factors and shows significant variability in the market. Key determinants include the product grade (industrial grade, high-purity grade, or customized grade), raw material costs (such as the type and quality of monomers and esterifying agents), production process complexity (including polymerization and esterification control requirements), order quantity (bulk orders usually enjoy volume discounts), and supplier location and service. Generally, the price ranges from tens to hundreds of US dollars per kilogram; industrial-grade products for general applications are relatively low-cost, while high-purity or specially modified grades for high-end fields (such as advanced materials or precision chemical processing) tend to have higher prices. Specific pricing requires consultation with suppliers based on detailed technical requirements and order specifications.
